Quantum-classical correspondence of the Dirac matrices: The Dirac Lagrangian as a Total Derivative
S. Savasta, O. Di Stefano, O. M. Marago
The Dirac equation provides a description of spin 1/2 particles, consistent with both the principles of quantum mechanics and of special relativity. Often its presentation to stude…

Classical Origin of the Spin of Relativistic Pointlike Particles and Geometric interpretation of Dirac Solutions
S. Savasta, O. Di Stefano
Spin of elementary particles is the only kinematic degree of freedom not having classical corre- spondence. It arises when seeking for the finite-dimensional representations of the…
